Machine learning integration

You can easily connect your favorite machine learning framework with Label Studio by using Heartex SDK.

That gives you the opportunities to:

  • use model predictions as prelabeling
  • simultaneously update (retrain) your model while new annotations are coming
  • perform labeling in active learning mode
  • instantly create running production-ready prediction service

There is a quick example tutorial how to do that with simple image classification:

  1. Clone pyheartex, and start serving:
    git clone https://github.com/heartexlabs/pyheartex.git
    cd pyheartex/examples/docker
    docker-compose up -d
    
  2. Specify running server in your label config:
    "ml_backend": {
      "url": "http://localhost:9090",
      "model_name": "my_super_model"
    }
    
  3. Launch Label Studio with image classification config:
    python server.py -l ../examples/image_classification/config.xml
    

Once you're satisfied with prelabeling results, you can imediately send prediction requests via REST API:

curl -X POST -H 'Content-Type: application/json' -d '{"image_url": "https://go.heartex.net/static/samples/kittens.jpg"}' http://localhost:8200/predict

Feel free to play around any other models & frameworks apart from image classifiers! (see instructions here)
